AppTune – Per-App Settings

Open YouTube → swipe brightness up to 80%, volume to 70%, enable DND. Open Kindle → dim brightness to 30%, silence, turn on Night Shift. Open Spotify → just turn up volume, don't touch brightness.

You do this dozens of times a day. AppTune lets you do all of it with ONE TAP.

🎯 HOW IT WORKS

1. Create "presets" — sets of settings tailored to each app
2. Place AppTune widget on your home screen (1×1 or 2×2)
3. Tap the widget → settings change + target app launches in 0.5 seconds

One tap replaces five. Not auto-detect (iOS/Android don't allow it), not complex like Tasker — just a widget tile you tap like a regular app icon.

⚙️ 8 SETTINGS YOU CAN TUNE
